Definitions

  • the subject matter disclosed herein relates to preparing of solutions from stock solutions. More specifically the subject matter relates to a system for preparing solutions from stock solutions for chromatography application.
  • Chromatography is a well-established and valuable technique for separating chemical and biological substances and is widely used in research and industry, finding many applications in compound preparation, purification and analysis.
  • chromatography There are many different forms of chromatography, liquid chromatography being of particular importance in the pharmaceutical and biological industries for the preparation, purification and analysis of proteins, peptides and nucleic acids.
  • a typical liquid chromatography apparatus has an upright housing in which a bed of packing material, which is usually particulate in nature and consists of a porous medium, rests against a permeable retaining layer.
  • a liquid mobile phase enters through an inlet, for example at the top of the column, usually through a porous, perforated filter, mesh or frit, moves through the bed of packing material and is removed via an outlet, typically through a second filter, mesh or frit.
  • liquids of precisely known composition and/or other characteristics such as pH, ionic strength, viscosity, density etc. It is further not uncommon that the composition of the liquid should not only be at each moment precisely known and controlled, but also should vary with time in a precise and controlled manner.
  • Such liquids are usually obtained by mixing or blending two or more liquids with each other, typically using a blending system, usually an on-site blending system, which may provide for both isocratic and gradient blending modes (step gradient and linear gradient).
  • composition of liquids is of utmost importance
  • buffers having a specified pH and optionally also ionic strength are utilized, the pH and ionic strength of the eluent being the two most important parameters that control selectivity of protein separations in chromatography, such as on ion exchange resins.
  • Another such application is filtration.
  • the current systems include usage of multiple high pressure pumps to deliver different stock solutions such as acid, base and salt along with water to a T-joint for forming the buffer solution that needs to be delivered to the chromatography column.
  • characteristics of the buffer solution such as pH level and conductivity cannot be determined before supplying to the chromatography column. This is because sensors for determining these characteristics of the solution may not be able to tolerate a pressure level of the solution.
  • the sensors can accommodate only generally a pressure up to 7 bar i.e. 0.7 MPa.
  • the buffer solutions may not have desired characteristics or may have variation in characteristics such as pH level and conductivity.
  • the usage of high pressure pumps also adds to cost of the chromatography system.
  • the object of the invention is to provide an improved way of preparing buffer solutions, which overcomes one or more drawbacks of the prior art. This is achieved by a system for preparing buffer solutions for chromatography from stock solutions with a simple and convenient design as defined in the independent claim.
  • the system comprises a T-joint for preparing a buffer solution by mixing at least one first solution and a second solution.
  • the T-joint receives the second solution from a solution supply unit connected to the T-joint.
  • one or more low pressure pumps supply the one or more first solutions into the T-joint.
  • the high pressure pump collects the buffer solution and delivers it to a chromatography apparatus.

  • the system 100 includes a T-joint 102 for preparing a buffer solution.
  • the T-joint 102 may be but not limited to a mixing unit or blending unit.
  • the buffer solution may be formed using a first solution and a second solution.
  • the first solution is stored in a solution supply unit 104 and a low pressure pump 106 is used to collect and deliver the first solution to the T-joint 102.
  • the low pressure pump 106 may have high flow rate accuracy and thus correct concentration of the first solution is delivered into the T-joint 102.
  • the T-joint 102 is connected to the solution supply unit 108 holding the second solution.
  • a check valve (not shown in FIG.
  • the check valve may be provided connecting the T-joint 102 and the solution supply unit 104.
  • the check valve also avoids any mixing that may happen between the first solution and the second solution in the solution supply unit 108.
  • an inlet valve may be present between T-joint 102 and solution supply unit 108 and/or between low pressure pump 106 and solution supply unit 104.

  • the T-joint 102 may have internal condition equivalent to atmospheric pressure.
  • the T-joint 102 may include a magnetic stirrer for mixing the first solution and the second solution to form the buffer solution.
  • the T-joint 102 may include multiple configurations for mixing the first solutions and the second solution.
  • the buffer solution is pumped by a high pressure pump 110 that operates at a higher pressure as compared to the low pressure pump 106.
  • the high pressure pump 110 may operate at pressure varying from 0 to 20 mega pascals (mPa). This pressure variation between the low pressure pump 106 and the high pressure pump 110 enables the buffer solution to be collected.
  • the buffer solution then passes through one or more sensors such as a sensor 112 and a sensor 114.
  • the buffer solution flowing from the low pressure pump 106 is at a low pressure for instance lesser than a 0.7 MPa.
  • the sensors 112 and 114 can measure the characteristics of the buffer solution due to reduced pressure.
  • the sensor 112 monitors a pH level of the buffer solution and the sensor 114 monitors conductivity associated with the buffer solution.
  • the sensor 112 may have a capability of accommodating a pressure ranging from 5 to 6 bar.
  • the conductivity of the buffer solution refers to an electrical conductivity of the buffer solution.
  • the electrical conductivity can be determined by a salt concentration in the buffer solution.
  • the characteristics of the buffer solution are not the desired characteristics, then a feedback is provided so that flow-rate of the first solution and the second solution from the solution supply unit 104 and the solution supply unit 108, and the flow rate of the high pressure pump 110 respectively are adjusted. This result in changing the concentration of the buffer solution formed in the T-joint 102 to obtain the buffer solution with desired characteristics.

  • the system 200 is capable of preparing different buffer solutions having different concentration levels such as a low pH level, a low salt level, a high pH level, a high salt level, a high acidic level and a low acidic level.
  • the system 200 includes a solution supply unit 202 holding acid, a solution supply unit 204 holding salt and a solution supply unit 206 holding a base.

  • the flow rate of the acid, the base and the salt can be varied to deliver buffer solutions of different concentration levels.
  • the sensors 112 and 114 are capable of measuring the pH level and conductivity of the buffer solution.
  • the sensors 112 and 114 are positioned closer to the low pressure pumps 208, 210 and 212 between the high pressure pump 110 and the low pressure pumps 208, 210 and 212. Further it may be envisioned that sensors other than the sensors 112 and 114 may be placed closer to the low pressure pump 210 without deviating from the scope of this disclosure. As these sensors are closer to the low pressure pump 210 the operation of the sensors 112 and 114 are not affected by any high pressure and hence they can measure the characteristics of the buffer solution. Further the sensors 112 and 114 can also be used to provide feedback to the low pressure pumps 208, 210 and 212 for controlling the flow rate of the first solutions.
  • the low pressure pump 208 is set to control the flow rate of the acid from the container 202 at 0.2 ml/minute.

  • the high pressure pump 110 may need to pull the buffer solution at a flow rate of 10 ml/min. In this case the water directly flows into the T-joint 102 at a flow rate of 9.2 ml/min. In the T-joint 102 the base, salt and acid are mixed with water to form a buffer solution.
  • the buffer solution in the T-joint 102 is pumped by the high pressure pump 110.
  • the buffer solution may be monitored by the sensors 112 and 114 to determine a pH level and conductivity associated with the buffer solution. If the characteristics of the buffer solution are not the desired one then the flow rate of the solutions from the containers 202, 204 and 206 may be varied so that the buffer solution with the desired characteristics is obtained.
  • the buffer solution is pumped by the high pressure pump 110 and delivered to a chromatography column.

  • the high pressure pump 110 can be operated to control the flow rate of the buffer solution.
  • the above system for preparing buffer solutions for chromatography from first solutions is disclosed.
  • low pressure pumps are used to collect and deliver first solutions to a T-joint
